The Ottoman Empire contributed indirectly to the start of World War I

As the Ottoman Empire weakened, Balkan peoples and states sought independence or expanded territory, creating instability and competing national ambitions in southeastern Europe. This helped fuel the tensions that contributed to World War I, so choice A, Balkan calls for independence, is correct. The other choices describe events or effects that do not fit: the empire did not rapidly industrialize and cause a European depression, and it did not fight Austria-Hungary before the war began.
